  • The Dell'Abate Ristorante that Don Vizioso uses as his hideout is named after Gary Dell'Abate, the Howard Stern Show producer best known as "Baba Booey". The restaurant's logo features a buck-toothed person wearing a Roman headdress that is a caricature of Gary.
  • The Hignight Hotel is named after writer Gavin Hignight.
  • The back of Don Vizioso's flying throne has an "I Brake for Connie Francis" bumper sticker with the Italian flag on it. Connie Francis was a famous Italian-American movie singer in the late 1950s and early 1960s.
  • On the back of Don Vizioso's flying throne is a sticker that reads, "Sono Affamato!" This is Italian for "I'm hungry", a nod to the Don constantly eating and being overweight.
